( ODM/OEM are Welcome )  ( Click To Enlarged Image )

  

I. Introduction

    HP-2000D is a stage PA amplifier. Due to digital amplifier and switching power supply design,
it's high efficiency and weight becomes lighter than traditional analog amplifier & liner transformer design.
Furthermore, it is built in the new DSP technology. Through DSP design, it is much easier to get the precise
setting and more functions.

II. Features :

     1. Output power :
         200W @ 8 ohms stereo
         400W @ 4 ohms stereo
         800W @ 8 ohms bridged mode
     2. Fans for cooling.
     3. Class D high efficiency circuitry design.
     4. Mode selector switch for stereo, bridged mode operation.
     5. Ultra-low total harmonic distortion.
     6. Signal and Clip indicators to monitor performance.
     7. Short circuit, Thermal, DC protection and power on/off muting.
     8. Convection cooling system dissipates heat through the heat sink and chassis for noise-free operation.
     9. Front panel circuit – breaker switch.
   10. One rack unit.
   11. PWM switching power supply design.
   12. build-in Digital Signal Processor(Compressor & Limit & Crossover & Subsonic & EQ).
   13. PC Link control.
